JS

Answer 1

Answer:

$Area = 395.2cm^2$

Step-by-step explanation:

Given

The attached prism

Required

The surface area

This is calculated as:

$Area= 2(LW + LH + WH)$

Where:

$Length \to L=5.78$

$Width \to W=12.7$

$Height \to H=6.72$

So, we have:

$Area = 2(5.78 * 12.7 + 5.78 * 6.72 + 12.7 * 6.72)$

Using a calculator, we have:

$Area = 395.1832$

$Area = 395.2cm^2$ ---- approximated
